A dApp front-end that tells the truth about the chain.

Connecting a wallet is the easy part. We build the interface around it: transactions simulated before you sign, state tracked to real confirmations, and a UI that walks itself back when a block drops, instead of leaving a green checkmark on money that never moved.

Hit send. The wallet builds, simulates, signs, and broadcasts, then the block panel shows it land and stack confirmations. Only called done once the chain agrees.

When a block drops, the UI tells the truth.

A naive dApp shows a green checkmark and never takes it back. Trip a reorg and watch this one walk the state back to pending, then re-confirm on the canonical chain, honestly.

You see the outcome before you approve it.

The biggest way people lose money on-chain is signing something they didn't understand. So we dry-run every transaction and render the result as a plain confirmation, exactly what leaves, what returns, and which approvals are asked for.

Every field in the modal on the left is decoded from this dry run, not guessed from the calldata.

Every wallet, every chain, one integration.

Your users don't all hold the same wallet or live on the same chain. Pick a connector and see its flow. We wire them once, behind one interface.
